I have never used cut film is the reason that I am asking. It just seems that it would be a great pain in the posterior.
I have quite a lot of the film holders and have tried to use them, but for me it is just more hassle than it is worth. Certainly it is interesting to be able to view with the ground glass on the back, especially to see if the taking lens and the focus lens agree on focus or if you want to see what you are really getting with the number 3 Rolleinar
How many is "quite-a-lot". I already tote about five or three cameras around with me at any one time plus all the accessories that go with them plus film. It gets rather tiresome at times and if I didn't enjoy doing this I would chuck all down the drain and take up brain surgery for a past time.
